Description

Technical Field

[0001] This invention relates to the field of testing technology, specifically to a hole-type terminal testing device and testing method. Background Technology

[0002] In electrical engineering, terminals often refer to wiring terminals, also known as wire terminals. There are many types of terminals, and their main function is to transmit electrical signals or conduct electricity. Terminals play an important role in electrical connections, and their performance directly affects the connection stability and service life of wires. Therefore, before putting terminals into use, staff need to conduct a complete inspection of the terminals to ensure their quality.

[0003] In addition to having small dimensional errors, qualified terminals also need to have sufficient toughness. Terminals with good toughness can better cope with various stresses, reduce the risk of breakage, and thus ensure the stable connection of wires. Currently, the toughness of terminals is tested by bending. If the terminal can smoothly spring back to its original shape within a certain degree of bending, it is a qualified product.

[0004] Existing toughness testing methods all use impact testing equipment, which requires staff to continuously change the test objects. This repetitive work is not only tedious but also greatly affects testing efficiency. Furthermore, each terminal needs to undergo two separate processes: comprehensive dimensional testing and toughness testing, which results in further time waste and hinders production efficiency. Therefore, this invention proposes a hole-type terminal testing device and method. Summary of the Invention

[0059] S6. The conveyor belt drives the bearing mechanism to continue rotating. When the bearing mechanism moves to the position of the clamping linkage mechanism of the support component, the two clamping plates move away from each other.

[0060] S7. If the hole terminals on the two clamping plates fall off after they move away from each other, it means that the hole terminals are deformed after the pressure plate is pressed down, and the product is unqualified.

[0061] Compared with existing technologies, this solution has the following advantages: It is equipped with a first detection mechanism and a second detection mechanism. The combination of the two detection mechanisms can perform comprehensive testing on the hole terminals, combining the original size detection and toughness detection into one, and can actively screen out hole terminals that fail the toughness test. This not only reduces the difficulty of the detection work, but also effectively reduces the complicated operation of loading and unloading materials. At the same time, it saves the conversion time between the two detections and improves the detection speed, which also helps to improve production efficiency. The design is ingenious and convenient to use. Attached Figure Description

[0079] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0080] Please see Figures 1-4 This application provides the following technical solutions:

[0081] A hole-type terminal detection device for detecting Figure 1The device, which includes a base 1, comprises a housing 11 that is approximately a right-angled trapezoidal truncated shell. The housing 11 has an internal cavity, and openings are provided on its upper and horizontal sides. The upper opening allows for the placement or removal of the terminal 100, while the horizontal opening serves as a discharge outlet for rejecting defective terminals 100. A conveying mechanism 2 is installed within the cavity of the base 1, conveying the terminal 100 along a circular path. Several supporting mechanisms 3 are mounted on the conveying mechanism 2, each capable of holding one terminal 100. A first detection mechanism 4 and a second detection mechanism 5 are mounted on the base 1. The first detection mechanism 4 includes an image acquisition component 41 that can acquire images around the terminal 100 to be detected. The second detection mechanism 5 is positioned above the conveying path of the conveying mechanism 2 and can press down on the terminal 100 within the supporting mechanism 3. The image acquisition component 41 can be a line scan camera to perform omnidirectional scanning and inspection of the hole terminal 100. This determines whether the size of the hole terminal 100 conforms to production standards. By moving the image acquisition component 41, scanning can be performed from the side to the top of the hole terminal 100, thus completely detecting the size and thickness of the hole terminal 100, facilitating the control of the specific specifications of each hole terminal 100. The toughness of the hole terminal is tested using the downward pressure of the second detection mechanism 5.

[0082] Based on the above implementation scheme, a support assembly 12 is fixedly installed inside the cavity of the housing 11. The support assembly 12 is located below the moving path of the carrying mechanism 3 and can support the carrying mechanism 3 during conveying. A discharge assembly 13 is provided in the middle of the housing 11. The discharge assembly 13 is a slide inclined towards the horizontal side of the housing 11. The discharge assembly 13 can receive unqualified hole terminals 100. The unqualified hole terminals 100 fall onto the discharge assembly 13 and then slide out to the outside of the housing 11. The support assembly 12 includes a horizontal plate, which is set below the parallel part on the upper side of the conveyor belt 21. A discharge port is opened on the horizontal plate, and the upper end of the discharge assembly 13 is located below the discharge port. An arc-shaped plate is set on each side of the horizontal plate, and the arc-shaped plate corresponds to the arc-shaped part of the conveyor belt 21.

[0083] Based on the above implementation plan, see Figure 4 and Figure 6The conveying mechanism 2 includes a conveyor belt 21 that is generally annular. The conveyor belt 21 includes two parallel sections, and arc-shaped sections at the ends of the two parallel sections. An annular groove 14 is formed on the inner wall of the housing 11 corresponding to the conveyor belt 21. The bearing mechanism 3 includes a rectangular frame bearing frame 31. A connecting rod 311 is provided on the outer side of the frame of the bearing frame 31. The bearing frame 31 is connected to the conveyor belt 21 through the connecting rod 311, and the connecting rod 311 is slidably connected to the annular groove 14 on the inner wall of the housing 11. The conveyor belt 21 is linked with the drive assembly 22, which drives the conveyor belt 21 to move intermittently.

[0084] The hole terminal 100 is conveyed by the movement of the conveyor belt 21. When the conveyor belt 21 stops moving, the first detection mechanism 4 and the second detection mechanism 5 detect the hole terminal 100.

[0085] Based on the above implementation plan, see Figure 6 The supporting mechanism 3 also includes a clamping assembly 32, which is disposed within the supporting frame 31 and can clamp the hole-type terminal 100. The clamping assembly 32 includes two clamping plates 321, both of which are slidably connected to the supporting frame 31. The two clamping plates 321 can move closer to or further away from each other; each clamping plate 321 has a contoured structure corresponding to the hole-type terminal 100. A clamping plate connecting assembly 322 is disposed between the two clamping plates 321. The clamping plate connecting assembly 322 includes two clamping plate connecting rods 3221, each corresponding to one of the two clamping plates 321. One end of each clamping plate connecting rod 3221 is rotatably connected to a clamping plate 321, and the other end is rotatably connected to a clamping plate connecting block 3222. The clamping plate connecting block 3222 is disposed between the two clamping plates 321. A clamping plate guide 3223 is fixedly installed on the upper side of the clamping plate connecting block 3222. The clamping plate guide 3223 is a portal frame, and its lower end is fixedly connected to the clamping plate connecting block 3222. A sliding groove is provided on the outer side of the bearing frame 31, and the clamping plate guide 3223 is slidably connected to the bearing frame 31 through the sliding groove. The sliding direction of the clamping plate guide 3223 is perpendicular to the sliding direction of the clamping plate 321. A clamping plate reset member 3224 is provided between the clamping plate connecting block 3222 and the bearing frame 31. The clamping plate reset member 3224 is a spring that can reset the clamping plate connecting block 3222.

[0086] See Figure 5A clamping linkage structure 121 is provided on the support component 12 corresponding to the clamping component 32. The clamping linkage structure 121 is located on the upper horizontal side of the material discharge port. The clamping linkage structure 121 is an upwardly extending boss with arc-shaped transition surfaces on both sides. When the bearing frame 31 passes the clamping linkage structure 121, the clamping linkage structure 121 can lift the clamping plate connecting block 3222 upward. As the clamping plate connecting block 3222 moves upward, the two clamping plates 321 slide along the bearing frame 31 and move away from each other. As the clamping plates 321 move away from each other, the hole terminal 100 that does not meet the toughness standard falls onto the discharge component 13. The specific falling situation of the hole terminal 100 will be described in detail later. When the bearing mechanism 3 moves away from the clamping linkage structure 121, under the action of the clamping plate reset member 3224, the clamping plate connecting block 3222 moves downward to reset, and the clamping plates 321 move closer to each other to maintain the clamping force on the hole terminal 100.

[0087] It should be noted that, considering the image acquisition component 41 acquires images of the hole terminal 100, the upper surface of the clamping plate 321 is located above the upper surface of the support frame 31 to ensure that the hole terminal 100 on it will not cause the image acquisition component 41 to fail when it is on the horizontal side due to the frame structure of the support frame 31.

[0088] Based on the above implementation scheme, the second detection mechanism 5 includes a second detection bracket 53, which is fixedly mounted on the housing 11. A pressure rod 51 is mounted on the second detection bracket 53, located above the conveying path of the conveying mechanism 2. The pressure rod 51 can move vertically. A pressure plate 52 is fixedly mounted at the lower end of the pressure rod 51. The pressure plate 52 is used to press down the hole terminal 100 in the bearing mechanism 3. A pressing position 122 is provided on one side of the horizontal plate discharge port corresponding to the second detection mechanism 5, and a pad is provided at the pressing position 122 corresponding to the pressure plate 52.

[0089] Through this structure, at the material discharge port, the first detection mechanism 4 performs the first inspection on the hole-type terminal, mainly checking the size, thickness, and other shape standards of the hole-type terminal. Then, at the second detection mechanism 5, the pressure plate 52 presses down on the pressure position 122 of the hole-type terminal 100, causing the hole-type terminal to deform to a certain extent. The hole-type terminal 100 that meets the toughness standard can return to its original shape; otherwise, it will deform and dent. When the bearing mechanism 3 rotates back to the material discharge port position, under the action of the aforementioned clamping linkage structure 121, the spacing of the clamping plates 321 increases. The undeformed hole-type terminal remains in the clamping plate 321, while the deformed hole-type terminal 100 falls off due to its shortened overall length and is then discharged.

[0090] Based on the above implementation scheme, the inner side of the conveyor belt 21 of the conveying mechanism 2 is provided with continuous teeth. The drive assembly 22 includes a main drive wheel 221 located in the middle of the annular area of ​​the conveyor belt 21. The main drive wheel 221 is linked to a motor and is an incomplete gear, with its gear portion covering approximately one-third of the entire circumference. The main drive wheel 221 can mesh with the teeth on the inner side of the conveyor belt 21. A driven wheel 222 is provided at each end of the annular structure of the conveyor belt 21. Through this structure, the intermittent movement of the conveyor belt 21 is achieved.

[0091] Based on the above implementation scheme, a conveying linkage structure 223 is provided on the conveyor belt 21. The device also includes a detection linkage mechanism 6, which is linked with the conveying linkage structure 223. When the conveyor belt 21 stops moving, the detection linkage mechanism 6 can be linked with the first detection mechanism 4 and the second detection structure 5.

[0092] In this scheme, the conveying linkage structure 223 is a set of levers installed on one side of the conveyor belt 21, with the levers of the set distributed along the conveyor belt 21. (See also...) Figure 7 The detection linkage mechanism 6 includes a first linkage ring 61 and a second linkage ring 62, both of which are annular and rotatably connected to the housing 11. Inclined actuation grooves are distributed on the inner side of the first linkage ring 61 corresponding to the conveyor linkage structure 223. When the conveyor belt 21 moves, the levers of the conveyor linkage structure 223 enter the actuation grooves one by one, thereby driving the first linkage ring 61 to rotate. The second linkage ring 62 is parallel and coaxially arranged with the first linkage ring 61. A first detection frame 41 is arranged between the first linkage ring 61 and the second linkage ring 62. The first detection frame 41 is a crossbar structure, with its two ends fixedly connected to the first linkage ring 61 and the second linkage ring 62, respectively. A first image acquisition component 41 is mounted on the first detection frame 41.

[0093] In addition, see Figure 3A linkage reset component 63 is provided on one side of the second linkage ring 62. The linkage reset component 63 includes an arc-shaped rod, with an arc-shaped spring sleeved on the outside of the arc-shaped rod. A push plate is provided on the side of the second linkage ring 62 facing the arc-shaped rod. The push rod and the arc-shaped rod are slidably connected, and one end of the arc-shaped spring abuts against the push plate. When the second linkage ring 62 rotates under the drive of the conveyor belt 21, the arc-shaped spring is compressed. It should be noted that there is a gap between the lever groups of the conveyor linkage structure 223, and the gap is slightly larger than the width of the actuation groove. When the conveyor belt 21 stops, the gap position of the lever group can reach the position of the first linkage ring 61. At this time, because the conveyor belt 21 stops moving, the lever cannot enter the actuation groove. The linkage reset component 63 resets, thereby driving the first linkage ring 61 and the second linkage ring 62 to rotate in opposite directions and reset. The first linkage ring 61 and the second linkage ring 62 must also be able to rotate to the horizontal side of the first image acquisition component 41 facing the hole terminal 100 under the drive of the conveyor belt 21.

[0094] Based on the above implementation scheme, and considering the commonality of the power structure, the pressure rod 51 of the second detection mechanism 5 and the second linkage ring 62 are linked. When the second linkage ring 62 is reset, the pressure rod 51 can drive the pressure plate 52 to perform a pressing and reset action.

[0095] This solution provides a specific linkage method; see [link / reference] Figure 8 and Figure 9 The second linkage ring 62 has a beveled tooth surface, and a second linkage member 54 is correspondingly provided to the second linkage ring 62. The second linkage member 54 is rotatably connected to the second detection bracket 53. The lower part of the second linkage member 54 has a bevel gear structure that can mesh with the second linkage ring 62. A linkage block 55 is provided on the inner wall of the second linkage member 54, and a spiral groove 56 is provided on the rod body of the pressure rod 51. Furthermore, a limiting rod 57 is provided on the outer side of the rod body of the pressure rod 51, and the limiting rod 57 is vertically slidably connected to the second detection bracket 53. The function of the limiting rod 57 is to restrict the pressure rod 51 to only move vertically and not rotate. The second linkage member 54 is designed to rotate only when the second linkage ring 62 is reset.

[0096] Through this structure, during the resetting process of the second linkage ring 62, the second linkage member 54 is driven to rotate, causing the drive block 55 to slide along the spiral groove 56, thereby driving the pressure rod 51 to perform a downward and upward action.

[0097] Based on the above implementation scheme, this scheme proposes the following two implementation structures for the unidirectional action structure of the second linkage 54.

[0098] The first type involves a cylindrical upper part of the second linkage 54, with a linkage block 55 inside. The lower part is connected to a bevel gear 58 via a one-way bearing. When the conveyor belt 21 indirectly drives the second linkage ring 62 to rotate, the one-way bearing allows the bevel gear 58 to rotate independently without rotating the upper cylindrical part of the second linkage 54. When the second linkage ring 62 resets, it drives the bevel gear 58 to rotate, at which point the one-way bearing allows the bevel gear 58 to drive the upper cylindrical part to rotate synchronously.

[0099] The second type is as follows Figure 9 As shown, the second linkage 54 is a cylindrical structure with a linkage block 55 inside. A bevel gear 58 is located at the lower part of the second linkage 54, and one edge of the teeth of the bevel gear 58 is rotatably connected to the periphery of the cylinder, with a torsion spring at the connection point. When the conveyor belt 21 indirectly drives the second linkage ring 62 to rotate, the second linkage ring 62 actuates the teeth to rotate, and the second linkage 54 does not rotate. When the second linkage ring 62 rotates in the opposite direction, the teeth cannot rotate, thus causing the second linkage 54 to rotate.

[0100] Based on the above implementation scheme, and corresponding to the aforementioned detection device, this scheme provides a detection method, including the following steps:

[0101] S1. Place the hole terminal 100 to be tested on the clamping plate 31 in the bearing mechanism 3;

[0102] S2. The conveyor belt 21 of the conveying mechanism 2 is used to intermittently convey the carrying mechanism 3;

[0103] S3. When the conveyor belt 21 of the conveying mechanism 2 stops moving, there is a bearing mechanism 3 at the first detection mechanism 4 and the second detection mechanism 5 respectively.

[0104] S4. The image acquisition component 41 of the first detection structure 4 moves around the hole terminal 100 in its corresponding support mechanism 3 and acquires images during the movement.

[0105] S5. The pressure plate 52 of the second detection mechanism 5 applies downward pressure to the hole terminal 100 in the bearing mechanism 3 below it under the action of the pressure rod 51.

[0106] S6. The conveyor belt 21 drives the bearing mechanism 3 to continue rotating. When the bearing mechanism 3 moves to the position of the clamping linkage mechanism 121 of the support component 12, the two clamping plates 321 move away from each other.

[0107] S7. If the hole terminal 100 on the two clamping plates 321 falls after they move away from each other, it means that the hole terminal 100 is deformed after the pressure plate 52 is pressed down, and it is a defective product.
